Tetralogy of Fallot: Comprehensive Guide to Diagnosis & Treatment
Introduction
Tetralogy of Fallot (TOF) is a congenital heart defect that disrupts the normal flow of blood through the heart. First described by French physician Étienne-Louis Arthur Fallot in 1888, this condition is defined by four specific heart abnormalities that occur together. These abnormalities hinder the heart’s ability to pump oxygen-rich blood to the body, leading to various health issues if left untreated. However, advances in medical science have made it possible to diagnose and treat Tetralogy of Fallot, significantly improving patient outcomes.
This article provides a comprehensive overview of Tetralogy of Fallot, covering its risk factors, symptoms, diagnostic tests, treatment options, and ways patients can manage symptoms at home. Our goal is to help patients and their families understand the condition and feel empowered to make informed health decisions.
Definition of Tetralogy of Fallot
Tetralogy of Fallot is a congenital heart condition involving four heart defects that result in poor oxygenation of the blood. This article will explore the risk factors, symptoms, diagnostic tests, treatment options, and home management strategies for Tetralogy of Fallot.
Description of Tetralogy of Fallot
Tetralogy of Fallot is a complex congenital heart defect characterized by four specific abnormalities:
- Ventricular Septal Defect (VSD): A hole between the two lower chambers (ventricles) of the heart.
- Pulmonary Stenosis: Narrowing of the pulmonary valve, reducing blood flow from the heart to the lungs.
- Right Ventricular Hypertrophy: Thickening of the right ventricle’s muscular walls due to the increased effort required to pump blood through the narrowed pulmonary valve.
- Overriding Aorta: The aorta is positioned over both the left and right ventricles, allowing oxygen-poor blood to flow into the aorta and out to the body.
These abnormalities cause oxygen-poor blood to be pumped to the body, leading to symptoms like cyanosis (a bluish tint to the skin, lips, and nails) and difficulty breathing. Without treatment, Tetralogy of Fallot can result in serious complications, including heart failure, stroke, and developmental delays.
Tetralogy of Fallot is one of the most common congenital heart defects, occurring in approximately 1 in 2,500 live births and accounting for about 10% of all congenital heart defects. While the condition can be life-threatening if untreated, advances in surgical techniques have greatly improved the prognosis, with most patients living into adulthood after corrective surgery.
Risk Factors for Developing Tetralogy of Fallot
Lifestyle Risk Factors
Although Tetralogy of Fallot is a congenital condition, certain lifestyle factors during pregnancy can increase the risk of a baby being born with this heart defect. Pregnant women who smoke, consume alcohol, or use illicit drugs are at higher risk of having a child with congenital heart defects, including Tetralogy of Fallot. Poor maternal nutrition, particularly a lack of essential vitamins like folic acid, may also contribute to the development of heart defects in the fetus.
It is crucial for pregnant women to manage chronic conditions like diabetes. Uncontrolled blood sugar levels during pregnancy can increase the risk of congenital heart defects, including Tetralogy of Fallot. Maintaining a healthy lifestyle, including a balanced diet, regular exercise, and avoiding harmful substances, can help reduce the risk of congenital heart defects.
Medical Risk Factors
Certain medical conditions in the mother can increase the risk of Tetralogy of Fallot in the baby. For instance, maternal infections during pregnancy, such as rubella (German measles), are linked to a higher risk of congenital heart defects. Women with phenylketonuria (PKU) who do not follow a strict low-phenylalanine diet during pregnancy are also at higher risk of having a child with heart defects.
Additionally, mothers with preexisting heart conditions or a family history of congenital heart defects may have a higher likelihood of giving birth to a child with Tetralogy of Fallot. Women with known medical conditions should work closely with their healthcare provider to manage their health during pregnancy and reduce the risk of complications.
Genetic and Age-Related Risk Factors
Genetics play a significant role in the development of Tetralogy of Fallot. Certain genetic disorders, such as Down syndrome and DiGeorge syndrome, are associated with a higher risk of congenital heart defects, including TOF. If a parent has a congenital heart defect, the likelihood of their child being born with one also increases.
Advanced maternal age (over 35 years) is another risk factor for congenital heart defects. As a woman’s age increases, so does the risk of chromosomal abnormalities, such as Down syndrome, which in turn raises the likelihood of heart defects like Tetralogy of Fallot. Genetic counseling may be recommended for families with a history of congenital heart defects or other genetic conditions to assess the risk of passing these conditions on to their children.
Clinical Manifestations of Tetralogy of Fallot
Cyanosis
Cyanosis, or a bluish tint to the skin, lips, and nails, occurs in about 85% of patients with Tetralogy of Fallot. This symptom is due to low oxygen levels in the blood. In Tetralogy of Fallot, structural abnormalities like the ventricular septal defect (VSD) and pulmonary stenosis cause oxygen-poor blood to mix with oxygen-rich blood. As a result, less oxygen is delivered to the body, leading to cyanosis. Cyanosis is often more noticeable during infancy, especially when the baby is crying or feeding, but it can persist throughout life if untreated.
Difficulty Breathing
Difficulty breathing, or dyspnea, affects approximately 70% of individuals with Tetralogy of Fallot. This occurs because the heart struggles to pump enough oxygenated blood to meet the body’s needs. The narrowed pulmonary valve restricts blood flow to the lungs, reducing the amount of oxygen that can be absorbed. Patients may experience shortness of breath during physical activity or even at rest. In infants, this can manifest as rapid breathing or difficulty feeding.
Fatigue
Fatigue is reported in about 60% of patients with Tetralogy of Fallot. It is often related to the heart’s inability to pump sufficient oxygenated blood to the muscles and tissues. This lack of oxygen leads to feelings of tiredness and weakness, particularly during physical exertion. Children with Tetralogy of Fallot may tire easily during play, while adults may find it difficult to perform daily activities without becoming fatigued.
Poor Weight Gain
Poor weight gain is observed in approximately 50% of infants with Tetralogy of Fallot. Infants with this condition often struggle to feed effectively due to difficulty breathing and fatigue, making it hard to consume enough calories. Additionally, the body may use more energy to compensate for the heart’s inefficiency, further contributing to poor growth. Failure to thrive is a common concern in babies with untreated Tetralogy of Fallot.
Heart Murmur
A heart murmur is present in nearly 100% of patients with Tetralogy of Fallot. This is often the first sign that prompts further investigation into the condition. The murmur is caused by turbulent blood flow through the narrowed pulmonary valve and the ventricular septal defect. It is typically detected during a routine physical exam using a stethoscope. While a heart murmur is not dangerous on its own, it is a key indicator of underlying heart abnormalities.
Clubbing of Fingers
Clubbing of the fingers occurs in about 30% of patients with Tetralogy of Fallot, usually in older children or adults with untreated or partially treated conditions. Clubbing refers to the enlargement of the fingertips and a downward curving of the nails. It is caused by chronic low oxygen levels in the blood, which leads to changes in the soft tissue of the fingers. This symptom tends to develop gradually over time.
Irritability
Irritability is common in infants and young children with Tetralogy of Fallot, affecting around 40% of patients. It is often a result of low oxygen levels in the blood, which can lead to discomfort and restlessness. Babies may cry more frequently and have difficulty calming down, especially when experiencing cyanosis or difficulty breathing. Parents may notice that their child becomes particularly irritable during feeding or physical activity.
Fainting Spells
Fainting spells, or syncope, occur in about 20% of patients with Tetralogy of Fallot. These episodes are caused by a sudden drop in oxygen levels in the blood, leading to a temporary loss of consciousness. Fainting is more likely to occur during periods of exertion or stress when the heart is working harder to pump blood. This symptom can be alarming and may require immediate medical attention.
Exercise Intolerance
Exercise intolerance is reported in approximately 50% of children and adults with Tetralogy of Fallot. It refers to the inability to engage in physical activity without experiencing symptoms such as shortness of breath, fatigue, or dizziness. The heart’s reduced ability to oxygenate the blood limits the body’s capacity to perform strenuous activities. Children may avoid physical play, and adults may find it difficult to engage in exercise or even routine tasks.
Tet Spells
Tet spells, or hypercyanotic spells, are episodes of severe cyanosis that occur in about 25% of patients with Tetralogy of Fallot, particularly in infants. These spells are triggered by a sudden decrease in oxygen levels in the blood, often during crying, feeding, or physical exertion. During a tet spell, the child may become extremely blue, have difficulty breathing, and lose consciousness. Tet spells are a medical emergency and require immediate intervention to increase oxygen levels and stabilize the patient.
Diagnostic Evaluation of Tetralogy of Fallot
The diagnosis of Tetralogy of Fallot typically begins with a physical exam and a review of the patient’s medical history. However, to confirm the diagnosis and assess the severity of the condition, several diagnostic tests are performed. These tests help visualize the heart’s structure, measure oxygen levels, and evaluate the heart’s electrical activity. Early diagnosis is crucial for planning treatment and improving outcomes, especially in infants and children. Below, we will discuss the key diagnostic evaluations used to diagnose Tetralogy of Fallot.
Echocardiogram
An echocardiogram, commonly referred to as an “echo,” is a non-invasive test that uses sound waves (ultrasound) to create detailed images of the heart. During the test, a technician places a small device called a transducer on the patient’s chest. The transducer sends sound waves through the chest, which bounce off the heart and create images on a monitor. An echocardiogram allows doctors to see the heart’s chambers, valves, and blood flow in real-time.
This test is particularly important for diagnosing Tetralogy of Fallot because it can clearly show the four key abnormalities: the ventricular septal defect (VSD), pulmonary stenosis, right ventricular hypertrophy, and the overriding aorta. The echocardiogram also helps assess the severity of the condition and determine whether surgery is needed. It is a safe and painless procedure that can be performed on patients of all ages, including newborns.
Results that Indicate Tetralogy of Fallot
If the echocardiogram shows a large ventricular septal defect, a narrowed pulmonary valve, and an overriding aorta, these findings are indicative of Tetralogy of Fallot. The test may also reveal thickening of the right ventricle due to the extra work the heart is doing to pump blood. In some cases, the echocardiogram may show additional heart defects, which can affect the treatment plan. If the test results are unclear, further imaging tests, such as a cardiac MRI, may be needed to confirm the diagnosis. If the echocardiogram does not show any abnormalities but symptoms persist, other diagnostic tests should be considered.
Chest X-ray
A chest X-ray is a simple imaging test that takes pictures of the heart, lungs, and chest bones. During the test, the patient stands in front of an X-ray machine, and a technician takes images from different angles. The X-ray can show the size and shape of the heart, as well as any abnormalities in the lungs or blood vessels. Although a chest X-ray is less detailed than an echocardiogram, it is still useful for providing an overall view of the heart’s structure.
In patients with Tetralogy of Fallot, a chest X-ray may show an enlarged right ventricle, which gives the heart a characteristic “boot-shaped” appearance. This is due to the thickening of the right ventricle as it works harder to pump blood. The X-ray may also show reduced blood flow to the lungs, which is a result of the narrowed pulmonary valve. While a chest X-ray alone cannot confirm the diagnosis, it can provide important clues that suggest the presence of Tetralogy of Fallot.
Results that Indicate Tetralogy of Fallot
A chest X-ray that shows a boot-shaped heart and decreased pulmonary blood flow is highly suggestive of Tetralogy of Fallot. These findings, combined with clinical symptoms such as cyanosis and a heart murmur, often prompt further testing, such as an echocardiogram or cardiac MRI. If the chest X-ray does not show any abnormalities but the patient continues to experience symptoms, additional tests should be performed to rule out other heart conditions.
Electrocardiogram (ECG)
An electrocardiogram (ECG or EKG) is a test that measures the electrical activity of the heart. Small electrodes are placed on the patient’s chest, arms, and legs, which detect the heart’s electrical signals. These signals are recorded on a graph, allowing doctors to see how the heart is beating. An ECG is a quick and painless test that can provide important information about the heart’s rhythm and function.
In patients with Tetralogy of Fallot, the ECG may show signs of right ventricular hypertrophy, which occurs when the right side of the heart becomes thickened due to the extra work it has to do. The ECG may also show abnormal heart rhythms, known as arrhythmias, which can be a complication of Tetralogy of Fallot. While an ECG cannot diagnose Tetralogy of Fallot on its own, it is a useful tool for assessing the heart’s electrical activity and identifying potential complications.
Results that Indicate Tetralogy of Fallot
ECG results that show right ventricular hypertrophy and abnormal heart rhythms are consistent with Tetralogy of Fallot. These findings, along with clinical symptoms and other test results, can help confirm the diagnosis. If the ECG is normal but the patient continues to have symptoms, further testing, such as a cardiac MRI or cardiac catheterization, may be needed to provide a more detailed view of the heart’s structure and function.
Cardiac MRI
A cardiac MRI is a non-invasive imaging test that uses magnetic fields and radio waves to create detailed images of the heart. During the test, the patient lies on a table that slides into a large machine. The MRI machine takes pictures of the heart from different angles, allowing doctors to see the heart’s structure and blood flow in great detail. Unlike an X-ray, an MRI does not use radiation, making it a safe option for patients of all ages.
Cardiac MRI is particularly useful for assessing the severity of Tetralogy of Fallot and planning surgery. It can provide detailed images of the ventricular septal defect, pulmonary stenosis, and other heart abnormalities. The MRI can also measure blood flow through the heart and lungs, helping doctors determine how well the heart is functioning. Cardiac MRI is often used in conjunction with other tests, such as an echocardiogram, to provide a comprehensive view of the heart.
Results that Indicate Tetralogy of Fallot
Cardiac MRI results that show a large ventricular septal defect, narrowed pulmonary valve, and an overriding aorta are indicative of Tetralogy of Fallot. The MRI may also show thickening of the right ventricle and abnormal blood flow patterns. These findings help doctors assess the severity of the condition and plan the appropriate treatment, which may include surgery. If the MRI does not show any abnormalities but symptoms persist, further testing may be needed to rule out other heart conditions.
What if All Tests are Negative but Symptoms Persist?
If all diagnostic tests come back negative but symptoms such as cyanosis, difficulty breathing, or fatigue continue, it is important to follow up with your healthcare provider. In some cases, additional testing may be needed to rule out other heart or lung conditions that can cause similar symptoms. Your doctor may recommend further imaging tests, such as a CT scan, or refer you to a specialist for a more in-depth evaluation. It is essential to continue monitoring your symptoms and seek medical advice if they worsen or new symptoms develop.
Health Conditions with Similar Symptoms to Tetralogy of Fallot
Ventricular Septal Defect (VSD)
A Ventricular Septal Defect (VSD) is a congenital heart condition where a hole exists in the septum that separates the heart’s two lower chambers (ventricles). This opening allows oxygen-rich blood from the left ventricle to mix with oxygen-poor blood from the right ventricle, forcing the heart to work harder and potentially leading to complications if left untreated.
How to Know if You Might Have a Ventricular Septal Defect vs. Tetralogy of Fallot
Both VSD and Tetralogy of Fallot involve a hole in the heart, but there are important distinctions. In Tetralogy of Fallot, the VSD is just one of four heart defects, while in isolated VSD, the hole is the primary concern. Symptoms like shortness of breath, fatigue, and poor growth in infants are common to both conditions, but cyanosis (bluish skin) is more typical of Tetralogy of Fallot and less common in isolated VSD unless the defect is large.
Doctors use echocardiograms and chest X-rays to differentiate between the two. In Tetralogy of Fallot, the echocardiogram reveals four characteristic defects, including pulmonary stenosis, while in isolated VSD, only the hole between the ventricles is visible. A chest X-ray in Tetralogy of Fallot may also show a “boot-shaped” heart, which is not seen in VSD.
Pulmonary Stenosis
Pulmonary stenosis is a condition where the pulmonary valve, which regulates blood flow from the heart to the lungs, becomes narrowed. This restriction increases pressure in the right ventricle and reduces the amount of oxygenated blood reaching the body.
How to Know if You Might Have Pulmonary Stenosis vs. Tetralogy of Fallot
Pulmonary stenosis is one of the four defects in Tetralogy of Fallot but can also occur as an isolated condition. Both can cause cyanosis, fatigue, and shortness of breath, especially during physical activity. However, isolated pulmonary stenosis lacks the ventricular septal defect and overriding aorta seen in Tetralogy of Fallot.
An echocardiogram can help distinguish between the two. In isolated pulmonary stenosis, the test shows narrowing at the pulmonary valve without the other defects seen in Tetralogy of Fallot. A cardiac catheterization may also be used to measure pressure in the heart chambers. Elevated pressure only in the right ventricle suggests isolated pulmonary stenosis, while Tetralogy of Fallot affects multiple areas of the heart.
Transposition of the Great Arteries (TGA)
Transposition of the great arteries (TGA) is a congenital heart defect where the two main arteries leaving the heart (the aorta and pulmonary artery) are reversed. This abnormality causes oxygen-poor blood to circulate through the body and oxygen-rich blood to circulate through the lungs, leading to severe cyanosis and other complications.
How to Know if You Might Have Transposition of the Great Arteries vs. Tetralogy of Fallot
Both TGA and Tetralogy of Fallot cause cyanosis, making it difficult to distinguish between them based on symptoms alone. However, cyanosis in TGA is usually more severe and occurs soon after birth, while in Tetralogy of Fallot, it may worsen over time or during physical exertion.
Diagnostic tests like echocardiograms are essential for differentiation. In TGA, the echocardiogram shows the abnormal positioning of the arteries, with the aorta arising from the right ventricle and the pulmonary artery from the left ventricle. In contrast, Tetralogy of Fallot shows the four characteristic defects, including a ventricular septal defect and pulmonary stenosis. A chest X-ray in TGA may show an “egg on a string” appearance, which is not seen in Tetralogy of Fallot.
Coarctation of the Aorta
Coarctation of the aorta is a condition where the aorta, the large artery that carries blood from the heart to the rest of the body, is narrowed. This forces the heart to work harder to pump blood through the constricted area, leading to high blood pressure and potential heart damage over time.
How to Know if You Might Have Coarctation of the Aorta vs. Tetralogy of Fallot
Both coarctation of the aorta and Tetralogy of Fallot can cause symptoms like shortness of breath, fatigue, and poor growth in infants. However, cyanosis is more common in Tetralogy of Fallot, while coarctation of the aorta is more likely to cause high blood pressure, especially in the arms, and weak or absent pulses in the legs.
Doctors can differentiate between the two using an echocardiogram and blood pressure measurements. In coarctation of the aorta, the echocardiogram shows a narrowing of the aorta, while in Tetralogy of Fallot, the test reveals the four characteristic defects. Blood pressure measurements can also help; a significant difference between the blood pressure in the arms and legs suggests coarctation of the aorta.
Atrial Septal Defect (ASD)
An atrial septal defect (ASD) is a hole in the septum between the heart’s two upper chambers (atria). This allows oxygen-rich blood to flow from the left atrium to the right atrium, causing the heart to work harder and potentially leading to complications like heart failure or arrhythmias.
How to Know if You Might Have an Atrial Septal Defect vs. Tetralogy of Fallot
Both ASD and Tetralogy of Fallot can cause symptoms like shortness of breath, fatigue, and poor growth in infants. However, cyanosis is rare in ASD, while it is a hallmark of Tetralogy of Fallot. Additionally, ASD is more likely to cause arrhythmias (irregular heartbeats) as the child gets older, which is less common in Tetralogy of Fallot.
An echocardiogram is the primary test used to differentiate between the two. In ASD, the test shows a hole between the atria, while in Tetralogy of Fallot, the echocardiogram reveals the four characteristic defects, including a hole between the ventricles (VSD) rather than the atria. A chest X-ray may also show an enlarged right atrium in ASD, which is not typically seen in Tetralogy of Fallot.
Eisenmenger Syndrome
Eisenmenger syndrome is a complication of certain congenital heart defects, such as VSD or ASD, where high blood pressure develops in the lungs (pulmonary hypertension) due to long-standing abnormal blood flow. This condition can lead to cyanosis, shortness of breath, and heart failure.
How to Know if You Might Have Eisenmenger Syndrome vs. Tetralogy of Fallot
Both Eisenmenger syndrome and Tetralogy of Fallot can cause cyanosis, shortness of breath, and fatigue. However, Eisenmenger syndrome typically develops later in life as a result of untreated congenital heart defects, while Tetralogy of Fallot is present from birth. Additionally, Eisenmenger syndrome is often associated with symptoms of pulmonary hypertension, such as swelling in the legs and abdomen, which are less common in Tetralogy of Fallot.
An echocardiogram and cardiac catheterization can help differentiate the two. In Eisenmenger syndrome, the echocardiogram may show signs of pulmonary hypertension and a long-standing defect like VSD or ASD, while in Tetralogy of Fallot, the characteristic four defects will be present. Cardiac catheterization can measure the pressure in the pulmonary arteries, which is elevated in Eisenmenger syndrome but not typically in Tetralogy of Fallot.
Treatment Options for Tetralogy of Fallot
Medications
Prostaglandin E1
Prostaglandin E1 helps keep the ductus arteriosus open, a small blood vessel in the heart that normally closes after birth. Keeping it open improves blood flow in babies with Tetralogy of Fallot.
Prostaglandin E1 is typically used in newborns with severe Tetralogy of Fallot to maintain adequate oxygen levels until surgery. It is administered intravenously in a hospital setting.
This medication stabilizes the baby’s condition by improving oxygenation, but it is a temporary measure until surgery can be performed.
Beta-blockers
Beta-blockers slow the heart rate and reduce the heart’s workload. They manage symptoms like “tet spells,” sudden episodes of cyanosis caused by reduced oxygen levels.
Beta-blockers, such as propranolol, are often prescribed to children with Tetralogy of Fallot who experience frequent tet spells. They are taken orally and can be used long-term to prevent these episodes.
Patients taking beta-blockers may experience fewer and less severe tet spells, leading to improved oxygen levels and overall comfort.
Diuretics
Diuretics, or “water pills,” help the body eliminate excess fluid by increasing urine output. This reduces the heart’s workload and prevents fluid buildup in the lungs.
Diuretics may be prescribed for patients with Tetralogy of Fallot who develop heart failure or fluid retention. They are typically taken orally and can be combined with other heart medications.
Diuretics improve breathing and reduce swelling, leading to better overall heart function.
ACE Inhibitors
Angiotensin-converting enzyme (ACE) inhibitors relax blood vessels and reduce blood pressure, making it easier for the heart to pump blood.
ACE inhibitors may be used in patients with Tetralogy of Fallot who develop heart failure or high blood pressure. They are taken orally and are typically used long-term.
Patients taking ACE inhibitors may experience improved heart function and reduced symptoms of heart failure, such as fatigue and shortness of breath.
Anticoagulants
Anticoagulants, or blood thinners, prevent blood clots from forming. This is important for patients with Tetralogy of Fallot who are at increased risk of clotting due to abnormal blood flow.
Anticoagulants may be prescribed to patients with Tetralogy of Fallot who have had surgery or are at risk for stroke or other clotting complications. They are taken orally or by injection.
By preventing blood clots, anticoagulants reduce the risk of serious complications such as stroke or pulmonary embolism.
Digoxin
Digoxin strengthens the heart muscle’s contractions, helping the heart pump more efficiently. It is used to treat heart failure and irregular heartbeats.
Digoxin may be prescribed to patients with Tetralogy of Fallot who develop heart failure or arrhythmias. It is taken orally and is usually part of a long-term treatment plan.
Patients taking digoxin may experience improved heart function and reduced symptoms of heart failure, such as fatigue and shortness of breath.
Oxygen Therapy
Oxygen therapy provides supplemental oxygen to increase oxygen levels in the blood. This can be particularly helpful during tet spells or when oxygen levels drop.
Oxygen therapy may be used in patients with Tetralogy of Fallot who experience frequent cyanosis or low oxygen levels. It is typically administered through a mask or nasal cannula.
Oxygen therapy provides immediate relief from low oxygen symptoms, helping stabilize the patient until further treatment is provided.
Calcium Channel Blockers
Calcium channel blockers relax blood vessels and reduce the heart’s workload. They are used to treat high blood pressure and certain types of arrhythmias.
Calcium channel blockers may be prescribed to patients with Tetralogy of Fallot who develop high blood pressure or arrhythmias. They are taken orally and are typically used long-term.
Patients taking calcium channel blockers may experience improved blood pressure control and reduced symptoms of arrhythmias.
Aspirin
Aspirin helps prevent blood clots by thinning the blood. It is often used in patients with heart conditions to reduce the risk of stroke or heart attack.
Aspirin may be prescribed to patients with Tetralogy of Fallot who are at risk for blood clots, particularly after surgery. It is taken orally and is typically used long-term.
By preventing blood clots, aspirin reduces the risk of serious complications such as stroke or heart attack.
Procedures
Surgical Repair
Surgical repair is the definitive treatment for Tetralogy of Fallot and involves correcting the heart’s structural abnormalities. This includes closing the ventricular septal defect (VSD) and widening the narrowed pulmonary valve or artery.
Surgical repair is typically performed during infancy or early childhood, although it can be done later if necessary. It is a major surgery requiring a hospital stay and careful post-operative monitoring.
After surgical repair, most patients experience significant improvement in oxygen levels and heart function, allowing them to lead more active, healthy lives.
Palliative Shunt
A palliative shunt is a temporary procedure that creates an alternative pathway for blood to reach the lungs, improving oxygen levels. It is often used as a bridge to full surgical repair.
Palliative shunts are typically used in newborns or infants who are not yet ready for full surgical repair. The procedure is done in a hospital setting and requires a short hospital stay.
This procedure improves oxygenation and stabilizes the patient until they are ready for definitive surgical repair.
Balloon Atrial Septostomy
Balloon atrial septostomy enlarges a small hole between the heart’s upper chambers (atria) to improve blood flow. This is usually done when blood flow to the lungs is severely restricted.
This procedure is typically performed in newborns or infants with very low oxygen levels who need immediate relief. It is done using a catheter inserted through a blood vessel and guided to the heart.
Balloon atrial septostomy provides temporary relief from symptoms and improves oxygen levels until more definitive treatment can be performed.
Improving Tetralogy of Fallot and Seeking Medical Help
Living with Tetralogy of Fallot requires ongoing care and lifestyle adjustments. Regular follow-ups with your healthcare provider are essential to monitor heart function and detect any complications early. A healthy diet rich in fruits, vegetables, and lean proteins supports overall heart health. Avoiding strenuous activities is important, as overexertion can trigger symptoms like shortness of breath or cyanosis.
Stress management techniques, such as meditation or breathing exercises, can help reduce the risk of tet spells. Staying hydrated is also crucial, as dehydration can worsen symptoms.
